<p>I want to compare rustdoc's current instruction count perf to beta. I don't know how to do that on the website though - there's no convenient dropdown and all the commits I tried gave NaN for the data, I think because perf might not run on beta backports? I don't know how to compare to 'the most recently nightly before the beta bump'.</p>

<p>well now I'm really confused, even <a href="https://github.com/rust-lang/rust/commit/dcef5ff372742eb3d8a1b5cbbc2141e757bc33d1">https://github.com/rust-lang/rust/commit/dcef5ff372742eb3d8a1b5cbbc2141e757bc33d1</a> isn't found</p>

<p>perf is clearly getting this info from <em>somewhere</em> though because it shows up on <a href="https://perf.rust-lang.org/dashboard.html">https://perf.rust-lang.org/dashboard.html</a></p>
